2 DOSAGE AND ADMINISTRATION Apply a thin layer of clobetasol propionate foam to the affected skin areas twice daily. clobetasol propionate foam is a super-high-potency topical corticosteroid; therefore, limit treatment to 2 consecutive weeks. Patients should not use greater than 50 grams per week or more than 21 capfuls per week because of the potential for the drug to suppress the hypothalamic-pituitary-adrenal (HPA) axis [see Warnings and Precautions (5.1 )]. Therapy should be discontinued when control is achieved. Clobetasol propionate foam should not be used with occlusive dressings unless directed by a physician. Clobetasol propionate foam is for topical use only. It is not for oral, ophthalmic, or intravaginal use. Avoid contact with eyes. Wash hands after each application. Avoid use on the face, groin, or axillae, or if skin atrophy is present at the treatment site. • Apply a thin layer to the affected skin areas twice daily.

5 WARNINGS AND PRECAUTIONS • Clobetasol propionate foam can cause reversible HPA axis suppression with the potential for glucocorticosteroid insufficiency during and after withdrawal of treatment. Risk factors include the use of high-potency topical corticosteroid, use over a large surface area or to areas under occlusion, prolonged use, altered skin barrier, liver failure, and use in pediatric patients. Modify use should HPA axis suppression develop. ( 5.1 , 8.4 ) • Clobetasol propionate foam may increase the risk of cataract and glaucoma. If visual symptoms occur, consider referral to an ophthalmologist. ( 5.2 ) • Clobetasol propionate foam is flammable. Avoid fire, flame, or smoking during and immediately following application. ( 5.4 ) 5.1 Effects on Endocrine System Clobetasol propionate foam can cause reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticosteroid insufficiency. This may occur during treatment or after withdrawal of treatment. Factors that predispose a patient to HPA axis suppression include the use of high-potency steroids, large treatment surface areas, prolonged use, use of occlusive dressings, altered skin barrier, liver failure, and young age. Evaluation for HPA axis suppression may be done by using the adrenocorticotropic hormone (ACTH) stimulation test. In a trial evaluating the effects of clobetasol propionate foam on the HPA axis, 13 subjects applied clobetasol propionate foam to at least 20% of involved body surface area for 14 days. HPA axis suppression was identified in 5 out of 13 subjects (38%) [ see Clinical Pharmacology (12.2) ] . If HPA axis suppression is documented, gradually withdraw the drug, reduce the frequency of application, or substitute with a less potent corticosteroid. Cushing’s syndrome and hyperglycemia may also occur due to the systemic effects of the topical corticosteroid. These complications are rare and generally occur after prolonged exposure to excessively large doses, especially of high-potency topical corticosteroids. Pediatric patients may be more susceptible to systemic toxicity due to their larger skin surface to body mass ratios [ see Use in Specific Populations (8.4) ]. 5.2 Ophthalmic Adverse Reactions Use of topical corticosteroids, including clobetasol propionate foam, may increase the risks of glaucoma and posterior subcapsular cataract. Glaucoma and cataracts have been reported in postmarketing experience with the use of topical corticosteroid products, including topical clobetasol products. Avoid contact of clobetasol propionate foam with eyes. Advise patients to report any visual symptoms and consider referral to an ophthalmologist for evaluation. 5.3 Allergic Contact Dermatitis Allergic contact dermatitis with corticosteroids is usually diagnosed by observing failure to heal rather than noting a clinical exacerbation. Such an observation should be corroborated with appropriate diagnostic patch testing. 5.4 Flammable Contents Clobetasol propionate foam is flammable. Avoid fire, flame, or smoking during and immediately following application.

8.1 Pregnancy Risk Summary There are no available data on clobetasol propionate foam use in pregnant women to inform of a drug-associated risk for adverse developmental outcomes. Published data report a significantly increased risk of low birth weight with the use of greater than 300 grams of potent or very potent topical corticosteroid during a pregnancy. Advise pregnant women of the potential risk to a fetus and to use clobetasol propionate foam on the smallest area of skin and for the shortest duration possible ( see Data ). In animal reproduction studies, increased malformations, such as cleft palate and skeletal abnormalities, were observed after subcutaneous administration of clobetasol propionate to pregnant mice and rabbits. No comparison of animal exposure with human exposure was computed. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Human Data Multiple observational studies found no significant associations between maternal use of topical corticosteroids of any potency and congenital malformations, preterm delivery, or fetal mortality. However, when the dispensed amount of potent or very potent topical corticosteroid exceeded 300 g during the entire pregnancy, use was associated with an increase in low birth weight infants [adjusted RR, 7.74 (95% CI, 1.49 to 40.11)]. In addition, a small cohort study, in which 28 sub-Saharan women using potent topical corticosteroids (27/28 used clobetasol propionate 0.05%) for skin lightening during pregnancy, noted a higher incidence of low birth weight infants in the exposed group. The majority of exposed subjects treated large areas of the body (a mean quantity of 60 g/month (range, 12 to 170 g) over long periods of time. Animal Data Embryofetal development studies conducted with clobetasol propionate in mice using the subcutaneous route resulted in fetotoxicity at the highest dose tested (1 mg/kg) and malformations at all dose levels tested down to 0.03 mg/kg. Malformations seen included cleft palate and skeletal abnormalities. In an embryofetal development study in rabbits, subcutaneous administration of clobetasol propionate resulted in malformations at doses of 0.003 and 0.01 mg/kg. Malformations seen included cleft palate, cranioschisis, and other skeletal abnormalities.

8.2 Lactation Risk Summary There is no information regarding the presence of clobetasol propionate in breast milk or its effects on the breastfed infant or on milk production. Systemically administered corticosteroids appear in human milk and can suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. It is not known whether topical administration of clobetasol propionate could result in sufficient systemic absorption to produce detectable quantities in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for clobetasol propionate foam and any potential adverse effects on the breastfed infant from clobetasol propionate foam or from the underlying maternal condition. Clinical Considerations To minimize potential exposure to the breastfed infant via breast milk, use clobetasol propionate foam on the smallest area of skin and for the shortest duration possible while breastfeeding. Advise breastfeeding women not to apply clobetasol propionate foam directly to the nipple and areola to avoid direct infant exposure.

6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: • Effects on Endocrine System [see Warnings and Precautions (5.1) ] • Ophthalmic Adverse Reactions [see Warnings and Precautions (5.2) ] Most common adverse reactions (≥ 4%) are application site burning and other application site reactions. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Glenmark Pharmaceuticals Inc., USA at 1 (888) 721-7115 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. In a controlled clinical trial involving 188 subjects with psoriasis of the scalp, there were no localized scalp adverse reactions reported in the subjects treated with clobetasol propionate foam. In 2 controlled clinical trials with clobetasol propionate foam in 360 subjects with psoriasis of non-scalp regions, localized adverse events that occurred in the subjects treated with clobetasol propionate foam included application site burning (10%), application site dryness (<1%), and other application site reactions (4%). In larger controlled trials with other clobetasol propionate formulations, the most frequently reported local adverse reactions have included burning, stinging, irritation, pruritus, erythema, folliculitis, cracking and fissuring of the skin, numbness of the fingers, skin atrophy, and telangiectasia (all less than 2%). 6.2 Postmarketing Experience Because adverse reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Local adverse reactions to topical corticosteroids may include: striae, itching, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, hypertrichosis, and miliaria. Ophthalmic adverse reactions may include: cataracts, glaucoma, increased intraocular pressure, and central serous chorioretinopathy.
